Thanks, this works

This sounded like if there would a workaround for +X. I tried the
following: define option "+", which takes argument. Then replace "+X"
with "-+X" in the command line. However:

% unset opts
% typeset -A opts
% set -- a -b something -+X -- -c
% zparseopts -A opts -D -E b: c +:
% echo "${(k)opts}"

% echo "${(v)opts}"
b+X

Weird, isn't it? With also a regular array:

% unset opts
% unset optsa
% typeset -A opts
% typeset -a optsa
% set -- a -b something -+X -- -c
% zparseopts -a optsa -A opts -D -E b: c +:
% echo ${(k)opts}

% echo ${(v)opts}
b+X
% echo $optsa
b - +X

With only regular array it's the same
